Lehle P-Split II Operating Instructions Manual page 20

Some units feature only balanced inputs and out-
puts, whereas others have only unbalanced inputs
and outputs. A Lehle P-Split II can be used to
connect these, also enabling you to separate the
ground connection (see "Types of signal line",
page 4).
What to do:
1. Connect the balanced or unbalanced signal
source to the input socket (1) of the Lehle P-
Split II.
2. Do not use the DIR socket (2).
3. Connect the balanced or unbalanced signal input
to the ISO socket (5).
4. Use the ground lift switch to determine the
position in which the most background noise is
eliminated.
5. There you go!
Note:
Unbalanced setups often include long cable runs
from a pedal board to an amp which, on large
stages, can be some distance away. Recording in
a mixing room via an amp located in a separate
18
soundproof booth will also necessitate long cable
runs. Long distances like these should be bridged
using balanced lines, in order to keep interference
as low as possible. The solution is simple: use the
Lehle Sunday Driver XLR to convert the unbal-
anced instrument signal to a balanced signal. Up
to 100m of cable can be connected to the XLR out-
put socket. The Lehle P-Split II can be used at
the end of the line to convert the balanced signal
back to an unbalanced signal for input to your
amp. This system makes it possible to convey the
signal across great distances without signal losses.
